STATUS AND TRENDS IN RESEARCH AIRCRAFT INSTRUMENTATION
The basic parts of an aircraft research instrumentation system are:sensors, amplifiers and recorders, a power source, and the necessarycontrols and switching. The preparation of an airborne instrumentedplatform is a systems engineering problem; factors of flight profile,sensor type and exposure, aircraft characteristics, recording media,power, installation of equipment, and reduction of the recorded data tousable form must all be considered. In practice, system components areoften selected because they happen to be available; the problem thenbecomes one of integrating the items into a usable system. Any researchinstrumentation system merits a careful analysis, from sensor to dataanalysis procedures, to ensure that data produced will justify the timeand money expended.
SENSORS
In most research systems, more effort is devoted to the developmentof sensors than to any other part of the system because of the unknownfactors that are involved. New, untried sensors and/or techniques mustbe tested to determine their ability for gathering atmospheric data.
If the aircraft platform is available only on a part-time or sharedbasis, the "in and out" requirement and lack of freedom to modify theaircraft structure impose severe constraints in mounting the equipment.Some of the new innovations of sensor installation involve extra remov-able nose sections, doors, and wing tips or tip tanks. An example isthe use of a rack installation to carry an external package. Generally,only sensors would be carried in the external package; the aircraft plat-form would provide the "universal" control, recording, and power facil-ities. It is conceivable that all necessary instrumentation, includingsensor, recorder, and power, could be carried as a self-contained unit.
Many sensors useful in meteorological research are available com-mercially. Requirements of users of meteorological sensors have createda trend toward faster response rates, easier calibration, and digitaloutputs for these instruments. However, the catalog data indicate thata large number of sensors are developed in-house, in contrast to otherportions of research instrumentation systems, which are generallyproven instruments developed for other uses, but which satisfy therequirements of meteorological research projects.
Similarly, some of the sensors used for atmospheric research wereoriginally developed for other purposes and later adapted for atmo-spheric research use. The spectrometer, radiometer, and stable plat-forms are examples. Although use of these sensors will continue, newconcepts are being applied directly to the field of atmospheric research,
1-2
as in the development of laser instrumentation specifically to studyparticulates and clear air turbulence, to determine aircraft altitude,and to determine sea state or snow surface roughness.
Within the near future, major advances in sensing appear imminentin two categories: particulate measurement, and the indirect observa-tion of many parameters by means of their inherent emissions. Particu-late measurement includes the collection or detection of the atmosphere'smost miniscule particles at altitudes from the surface to the greatestheights that aircraft can reach. It includes trapping these particlesin filters, on films, or in containers, and analyzing their compositionat ground laboratories. It also includes sampling their composition andconcentration, in real time, within the aircraft. For real-time sam-pling, sensors will select some physical, chemical, or electrical prop-erty of the particles, such as mass, phosphorescence, or nucleatingpropensity. Ground analysis will also be performed using these tech-niques, together with electron microscope techniques, and activationanalysis.
Emission measurements depend on the fact that all solids, liquids,and gases emit energy on a scale and at wavelengths related to theirthermal condition and thermal properties. Their emissions are greatestat a frequency determined by their temperature, and extend in both direc-tions from the peak in a known manner. Some emissions are essentiallyblackbody (e.g., the ground surface), while others (the gases) have adistinctly banded structure.
Ground or sea water temperature can now be sensed remotely withrelatively simple radiometers. More complicated, but still air transport-able, radiometers and spectrometers can measure cloud top temperatures,and vertical profiles of temperature and water vapor content when cloudsare absent. Semiactive techniques to measure atmospheric dust proper-ties are feasible, using the sun as the source of radiant energy.
Microwave radiometry is being applied to certain large-scaleradiation mapping projects. The techniques in the microwave region arecompletely different from those in other regions of the spectrum. Prob-lems of antenna design, cryogenic cooling, and elaborate signal process-ing take the place of the optical and detector problems associated withvisual and IR wavelength radiometry. At still lower frequencies,electromagnetic radiations by clouds and variations in the electricalproperties of the atmosphere will undoubtedly receive more study and willrequire very sensitive and stable detectors to operate at frequenciesranging from essentially direct current to hundreds of megacycles.
Still another sensor development appears to be necessary: theevolution of better directional stabilization for primary sensors whendirectionally precise observations from aircraft are required. Aircraftobservations of the sun, for instance, will require rough leveling bythe aircraft autopilot or an inertial platform, and fine pointing by aprecise sun-follower. The space age has given us the tools for this job;it is only a matter of adapting these tools to the aircraft environment
I-3
to achieve usable accuracies (1 arc min or less). A primary designproblem is the mass that must be stabilized. It is easy to design aninstrument whose sheer bulk will preclude aircraft use. On the otherhand, when aircraft flight is an initial goal, it is also relativelyeasy to limit the mass that must be pointed to a single mirror, lens,or detector. Thus, coordination between the scientist and the instru-mentation engineer, and detailed knowledge of the aircraft platform areessential from the very beginning of a project.
RECORDING METHODS
Great freedom of choice is possible in the selection of datarecording equipment. System requirements may dictate one or severalrecording methods. The most widely used methods are analog chart andphotographic recordings. Continuous analog records are popular becauseof their ready access, comparison, and preliminary evaluation by visualexamination. Most chart recorders in use are older laboratory-typeinstruments that also perform well in the aircraft environment, if spaceand weight are not a problem. Newer instruments offer improved porta-bility, smaller size, and many options on sensitivity, response, andpower requirements.
If more than a few parameters are processed, the data reductioneffort required with analog chart inputs becomes a serious problem.Several facilities utilize semiautomatic chart readers to convert re-corder deflections to digital form for further processing by a computer.Fully automatic chart digitizing devices are now available and should beconsidered if large volumes of analog chart data are to be processed.
For visible parameters (i.e., clouds, radar scopes, and the posi-tions of dials, switches, or indicators), cameras are popular recordingdevices. Photo recording systems are usually simple and inexpensive,and are often used for a backup record or for parameters not requiringhigh resolution and accuracy. However, the analysis of film records istime-consuming and tedius when considerable information is required.
Analog records can also be made on magnetic tape. Large, laboratory-type recorders have been used in aircraft of transport size, but smallportable recorders are availabble. Magnetic tape is a reliable recordingmedium and offers a much higher frequency response than chart recorders.The analog input must be converted to a frequency-modulated signal toretain amplitude accuracy, and subsequent playback requires additionalequipment to return the signal to its analog form and make a visiblerecord. During playback, it is possible to use an analog-to-digitalconverter and obtain a digital record suitable for computer processing.
A disadvantage of magnetic tape recording, whether analog or digital,is the lack of a visible record in real time. Therefore, the usual in-strumentation system includes the parallel metering or charting of a fewselected parameters to allow real-time evaluation.
I-4
Digital magnetic tape recorders of the computer type are found onlyin larger aircraft systems where a tremendous volume of data makes theadded size and complexity of this type of equipment worthwhile. Digitaldata systems have two definite advantages: first, the sensed data areconverted to a numeric value before recording, and retain their accuracyfrom this point on; second, once recorded, the data can be processedreadily with ground-based computer systems.
A recent innovation in the recorder field, the incremental digitalmagnetic tape recorder, promises to make digital recording more attrac-tive for use in all sizes of airborne, data systems. Unlike computertape transports, which require constant data rate and fixed tape speed,incremental (stepper) recorders record asynchronously (a character at atime) to maintain constant packing density. Steppers advance the tapeonly on receipt of a digital character, and record information receivedat any rate (fixed or variable) from 1 to 300 Hz. There are now manydifferent incremental magnetic recorders on the market, with their advan-tages of digital recording, tape reusability, high information packingdensity, and reliability at high data rates. Many of these recordersare small, compact units suited for aircraft installation or portableuse. Some incremental magnetic recorders can record directly incomputer-compatible format, thereby eliminating secondary conversion.Other less expensive recorders are not directly compatible.
INSTRUMENTATION POWER
Most instrumentation systems require some form of on-board electri-cal power, since the power required by research instruments usually dif-fers from the normal aircraft electrical power system. The standardprivate aircraft power system is 12 V dc; larger twin- and multi-engineaircraft use 28 V dc. Military aircraft have a combination of 28 V dcand 400 Hz ac power, with 400 Hz ac becoming the primary power system.In contrast, most readily available electronic equipment requires stan-dard household 115 V, 60 Hz ac power. For many years, rotary invertershave been used to bridge the gap between the dc power sources and theac power requirements of instruments. More recently, solid state in-verters have been developed which offer many advantages in size, weight,efficiency, and reliability. Conversion from dc to ac is the normal re-quirement for airborne instrumentation, but other conversions are alsooccasionally necessary.
All aircraft are limited in the amount of electrical power they cansupply for instrument use, and instrumentation installations are oftenpower-limited before they are space- or weight-limited. Batteries, ad-ditional aircraft-engine-driven generators, and self-contained auxiliarypower units are some of the means adopted to provide supplementary power.Some of the systems described on the following pages use gas turbine,400 Hz alternator auxiliary power units. One suggested possibility forauxiliary power generation is a fan-driven alternator mounted in theaircraft slipstream.

AIRCRAFT POSITION AND ATTITUDE
Most research projects need information about the location, atti-tude, and relative motion of the sensor platform. The basic aircraftinstruments provide indications of altitude, airspeed, heading, atti-tude, and time. Common additional requirements are such specializedinputs as angle of attack, acceleration, rate of climb, altitude aboveground level, roll, pitch, and yaw position and/or rates.
The most elementary way to determine the geographic location ofthe platform is by visual reference to the ground. Such visual naviga-tion is quite adequate for much of the low-level and local flying. Ifradio navigation is needed, the VOR/DME system available in the U.S.seems to offer the most utility to the average user. Accuracy obtain-able depends more on local conditions and the condition of receivingand transmitting equipment than on the initial equipment cost. Accu-racy can vary from ± 1 to + 4° in bearing, and from 1 to 2% in distance.Other radio navigation systems such as LORAN and CONSOLAN (long-rangenavigation) and Decca (short-range navigation) could be useful in someapplications.
Doppler and inertial navigation systems are being used by themilitary and by commercial airlines, and are found in a few researchaircraft platforms, but the cost and complexity of available equipmentlimit their use. The typical inertial guidance system provides contin-uous recordable outputs of aircraft pitch, roll, and true heading; air-craft ground track and ground track velocity; north-south and east-westvelocity; aircraft present position in latitude and longitude; andautopilot command outputs.
Ground-based radar is a useful tool for determining aircraft posi-tion and track, although its use restricts the aircraft to a fixedvolume of space which is limited by the range and accuracy capabilitiesof the ground-based radar (or radars). A particular advantage ofground-based radar in cloud physics and rainstorm research is the pos-sibility of a common reference for aircraft and "weather" radar trackinformation, which greatly facilitates data reduction.
Methods to record aircraft position must be selected with the over-all data reduction problem in mind. Manual recording is adequate inmany situations, using paper chart records, a voice record, or magnetictape. The pilot or equipment operator is the link between the aircraftinstruments, visual observation, or navigation equipment readouts, andthe physical record. Greater accuracy and reliability are possible bythe use of normal photographic techniques to obtain a record of aircraftinstrument readings at times of interest. In addition, photographs ofthe atmosphere surrounding the aircraft, or of the surface underneath,are a useful source of data for many experiments. In some experimentsit is necessary to obtain a continuous record of aircraft position and
1-6
altitude to accompany the other sensed data. A few aircraft instrumentshave electrical outputs suitable for recording, but in most cases theinstruments must be modified. If they cannot be modified, it is simplestto provide separate sensors whose outputs can be recorded directly.

THE PENNSYLVANIA STATE UNIVERSITY PROJECT SUMMARYCollege of Earth and Mineral SciencesDepartment of Meteorology503 Deike Building 1. An Investigation of the Dynamics and Micro-University Park, Pennsylvania 16802 physics of Clouds: Aircraft and surface networks
are employed to obtain coordinated observations ofSource: Charles L. Hosler, Dean the microphysics, dynamics, and environmental prop-
erties of shower situations which are compared toDate: 8/27/70 numerical models of precipitation processes. Defin-
itive experiments are being performed, both in thefield and laboratory, to aid in the assessment ofthe consequences of artificial modification ofclouds. Data derived from these programs are ulti-mately used to relate changes in the formation ofprecipitation as predicted by numerical calculations.
2. Atmospheric Turbulence: The properties and Hstructure of atmospheric turbulence are being studied with data obtained from measurement programsutilizing tower and aircraft instrumentation.
INSTRUMENTATION SUMMARY
The Aero Commander 680E is equipped with a completecloud physics instrumentation package. The instru-ment sensors primarily associated with in-cloudmeasurements are mounted in a removable pod underthe right wing. The sensors for standard meteoro-logical measurements are fuselage-mounted toincrease the operational flexibility of the aircraft.An identical pod under the left wing may be set upto carry two types of pyrotechnic seeding devices
or a continuous gelatin cloud-particle sampler.The removable sampling tube for the high-speedhydrometeor sampler projects through the roofof the fuselage. The camera is mounted at therear of the cabin. Cabinets containing the dataacquisition system and sensor signal condition-ing electronics are mounted to the floor behindthe copilot position. The data system isequipped with a crystal-controlled time base,programable gain and format switching, plusvarious event marks and manual data entries.Systems programming has been developed for thePSU IBM 360/67 computer to automatically reduceand output the data in various user-selectableformats.
